About this study

Official title: Study on Brain Structure and Function Imaging in Patients With Cerebral Venous Outflow Disturbance

Cerebral venous outflow disturbance can lead to cerebral hemodynamic disturbances, altered cerebrospinal fluid dynamics, cerebral venous blood stasis, increased cerebral venous pressure and decreased cerebral perfusion, cerebral white matter sparing-like changes, and widening of retinal vessel diameter. These changes are associated with numerous neurological signs and symptoms. Therefore, understanding the brain structural and functional changes in patients with cerebral venous outflow disturbance is essential to provide specific imaging evaluation indicators and new diagnosis and treatment methods for patients with cerebral venous return disorders.

Read the detailed description

Cerebral venous outflow disturbance can lead to cerebral hemodynamic disturbances, altered cerebrospinal fluid dynamics, cerebral venous blood stasis, increased cerebral venous pressure and decreased cerebral perfusion, cerebral white matter sparing-like changes, and widening of retinal vessel diameter. These changes are associated with numerous neurological signs and symptoms. A number of central nervous system disorders such as transient global amnesia, transient monocular blindness, primary labor headaches, and even Parkinson's have been reported to be closely associated with internal jugular vein stenosis. Other common clinical manifestations include sleep disturbances, tinnitus, tinnitus, headache, visual impairment, optic papilledema, hearing loss, cognitive decline and neck discomfort and even autonomic dysfunction. The main objective of this study is to investigate the structural and functional network changes in patients with cerebral venous outflow disturbance using different brain imaging techniques, to clarify the correlation between symptoms of cerebral venous outflow disturbance and brain structure and function; to identify areas with corresponding structural and functional changes in patients with cerebral venous outflow disturbance and or comorbid symptoms, and to provide specific imaging assessment indicators and new diagnostic and treatment tools for patients with cerebral venous outflow disturbance and comorbid symptoms.

Being tested
high-resolution 3D-T1, diffusion tensor imaging (DTI), resting-state functional magnetic resonance imaging (rs-fMRI), arterial spin labeling (ASL) perfusion magnetic resonance imaging (MRI), susceptibility-weighted images (SWIs)

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • high-resolution 3D-T1Radiation

    Subjects undergo a high-resolution 3D-T1 imaging to obtain structural images

  • diffusion tensor imaging (DTI)Radiation

    Subjects undergo a DTI imaging to obtain images of white matter lesions

  • resting-state functional magnetic resonance imaging (rs-fMRI)Radiation

    Subjects undergo rs-fMRI to investigate the differences in intra-regional brain activity and inter-regional functional connectivity

  • arterial spin labeling (ASL) perfusion magnetic resonance imaging (MRI)Radiation

    Subjects undergo arterial spin labeling (ASL) perfusion magnetic resonance imaging (MRI) to clarify the difference of cerebral blood flow (CBF) perfusion in certain regions

  • susceptibility-weighted images (SWIs)Radiation

    Subjects undergo susceptibility-weighted images (SWIs) to segment the vein network

Questions about this trial

What is this clinical trial studying?

An observational study of Abnormal Cerebral Venous Sinus Morphology and Internal Jugular Vein Stenosis, run by Capital Medical University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 19 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Xunming Ji (010-83199430, jixm@ccmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

voxel-based morphometry (time frame: at admission). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05820165, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Apr 2023.
